A Universal Standard for Investigation
1. Observation
2. Question
3. Hypothesis
4. Method
5. Result
6. Conclusion
What is the Scientific Method? - A tool of inquiry.
A logical serious of steps that allow you to move through the process.
Why is it important as a tool of investigation?
Ask a question- do background research- construct hypothesis - test with an experiment -analyze data and results - hypothesis is true/false- REPORT RESULTS!
Questions to ask.
Control group? experimental group? why?
Step 1: "The Problem"
Step 2: Hypothesis - an educated guess, intended explanation to the problem.
Step 3: Establish a "Method or Procedure"
- Make a logical series of steps to test hypothesis and these steps produce a controlled experiment
- Dependent variable happens based off of controlled variable.
- Need to clearly define variables and steps taken
- Independent variable is the single issue you are examining.
- Controlled group V. Experimental group.
Experiments should be reproducible!
Step 4: Forming "Conclusions"
- Negative conclusions- data does not support your original hypothesis
- Positive conclusion- the data strongly supports your original hypothesis.
- Summarize and evaluate your experiment. What would you do differently?
- Suggest changes in the experimental procedure? Errors?
- Random error- data results move around randomly- hard to eliminate.
